Title: Noise suppression method for resistive and other measurement bridge - synchronously switching polarity of supply voltage and output capacitor, preventing application of measurement signal-dependent charge, while reducing small signal bandwidth
Inventor: KILLAT DIRK DIPL ING
IPC: G01R17/10
Filed: 1993-04-06
Abstract: The sign of the bridge (R1-R4) supply voltage is periodically changed, i.e. it is inverted. A capacitor (Cc) with two timer-controlled changeover switches is connected to the bridge output, i.e. in its diagonal, so that the capacitor electrode connections are reversed synchronously with the change in sign. The capacitor changeover ensures that no measurement signal-dependent charge is applied to the capacitor as a result of the timer-controlled changeover. The small signal bandwidth of the bridge output is simultaneously reduced. USE/ADVANTAGE - For damping noise in resistive measurement bridges. Electromagnetic noise on the lines to any type of bridge and any noise type uncorrelated with a measurement signal is reduced for any bridge type using method not requiring filters, modulators or demodulators.

Title: Method for producing a ULSI semiconductor device
Inventor: JEONG JAE SEUNG
IPC: H01L21/311
Filed: 1993-09-16
Abstract: A method for producing a semiconductor device comprises a process for forming a contact opening and a flattening or levelling process, in each of which etching is carried out by sputtering. In the process for forming the contact opening, a conductive layer (100) is first produced on a semiconductor substrate, after which an insulation layer (1) is formed on one surface of the conductive layer (100). A predetermined part of the insulation layer (1) is then removed to form a contact opening (2), as a result of which the underlying conductive layer (100) is revealed. The insulation layer (1) is then etched by sputtering, in order to bevel the lateral wall of the contact opening (2). During the flattening process, on the other hand, a first flattening layer (23) is applied with the aid of a LPCVD process onto projecting structures of a semiconductor substrate (10), and then etched by sputtering, in order to obtain slopes with an inclination of approximately 45 DEG  in the region of steps. With the aid of a plasma-enhanced CVD process, a second flattening layer is then produced on the first flattening section, with sufficient thickness for the purpose of obtaining the desired planarity. The second flattening layer is then etched back to a desired thickness. <IMAGE>

Patent DE-4408334-A1 (DE)
Inventor: DOSTERT KLAUS PROF DR ING
IPC: H04B3/54
Filed: 1994-03-11
Abstract: On reception, a filtered and amplified reception signal (X) coupled from the current network, reaches a digital multiplier (5) after digital to analog conversion. The second input of the multiplier has a reference signal (Y) from a sample value memory (24) addressed by a cyclic address counter to fixed base length (20). Exactly four reference values (Y), corresponding to the in-phase and quadrature sample values of each L and H signal form, are allocated to each X value. The resulting products are accumulated in a ring structure of a summer (6), four registers (7,8,9,10) and a switch (11). After one signal form cycle, the in-phase components of the H and L bit are accumulated in two registers (9,10) and the quadrature components are accumulated in the other registers (7,8). By undoing the ring structure, the switch (11) feeds the four results from the registers (7-10) to a decision unit including a switch (13), a summer (14) and two registers (15,16).

Title: Protective fence for securing hazardous zones
Inventor: BRUEHL HANS GEORG
IPC: E04H17/16
Filed: 1994-05-12
Abstract: A protective fence for securing hazardous zones on machines or the like, having fence panels borne by posts or the like, is intended to be easily adaptable to the local conditions, with the result that relatively simple production from starting material is possible and also protective fences which have already been supplied and assembled may, if appropriate, be easily modified. The panels formed between the posts are thus intended to dispense with separate metal frames with welded-in fixed grid ceilings. Rather, the panels are intended to be designed as frame-free grid panels 4 comprising vertical and horizontal wires (5, 9, 10, 6) which are arranged in an orthogonal manner and are connected to one another at crossover locations, and provision is to be made, as the fastening elements for fitting said panels, for clamping plates which are braced against vertically running wires (6) of the grid panels. While the horizontal wires are selected with a diameter in the range of from 5 to 8 mm, use is made of vertical wires with a diameter in the range of from 4 to 6 mm, and the horizontal wires are connected to the vertical wires by welding, preferably spot welding, and special reinforcements are achieved in that the grid panels are provided, at least at their upper and/or lower ends, with two horizontal wires (5, 9) which are located opposite one another and project beyond the vertical wires (6) in each case. In particular, use may, if appropriate additionally, be made of flat-steel bars for stabilising purposes. <IMAGE>
